IMPROVED rLoUeH.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, FRANKLIN WATSON, of I-Iarrison, in the county of Winnebago, and 'State of Illinois,-

have invented a new and' improved Plough; and I do hereby declaro that th:` following is a full and exact description of the same, reference being had to the accompanying.draw-ings, and to the letters of reference marked thereon.

This inventionconsists of a plough of peculiar shape, so constructed that the share und mould-board change from side to side, being operated by a simple arrangement of springs.

To enable others to make and use my invention, I will new proceed to describe its construction and operation.

A represents a plough-beam of ordinary construction, and B the handles, which latter unite and terminate in a socket in the projection C, which'slopes upward from the plough-foot D. rIlhc latter is supported near its forward end by the standard E. The combination of the plough-foot, standard, beam, and handles may be,

termed the framework ofthe plough, to which are attached the share and mould-board and the devices foi-operating them. Upon the front end of the plough-foot is a pin, cl, which lits into a socket of corresponding-size in the triangular block f, arranged for the purpose on the forward end of the mould-board F. At the rear endof the foot is a socket, into which tits the corresponding projection on the support G, which divides, as shown, and hooksinto the eyes g of the mould-board. The rod II holds the support Gr firmly in position. The connection 0f the mould-board with the plough-foot, by means of the pin and socket at the forward end, and by means of the support G at the rear end, is such that the mould-board turns freely, and can be used on either side as desired. h represents a fiat spring attached tothewmder side of the plough-beam, and extending an equal distance on each side. Eachend terminates in V*a hook, which ts into the holes f in the mould-boardz' also represents a spring, attached in the same manner as l, and before it, the ends of which terminate in a curve in a downward direction, against which the mould-board presses when hooked bythe spring 7L, the function of whiclrs to'assist in turning the plonghshare and mould-board when desired.

The operation of my invention is as follows: The ploughman having reached the end nf the furrow, and desiring to change sides, raises the spring L with his foot, and the spring t' being thus allowed to act, throws the mould-board with considerable force, effecting a partial revolution. The handles being at the same time raised, and lifted to the proper side, the desiredl change is made quickly and easily. The 1nould-board in changing comes into its place with sufficient force to press in the spring 1.','and raise the spring t far enough to permit the latter to hook into the hole f, withoutY eii'ort on the part of the operator. The odge of the mouldboard at this point is-made slightly inclined to facilitate this operation.

The share and mould-board are so attached to eachother by means of nuts that the former can be readily removed when desired, and its place filled by a duplicate. The share, when in position, fits snugly against the standard E, this arrangement giving strength and iirmness where most needed. The share also is arranged in such manner that it acts as a Coulter, its position being such that the wear will always have a tendency to keepV it sharp. The mould-board F is of peculiar shape, it being such that there is no opportunityfor 'the earth to cling toits surface. I The angle between the lines of the mould-board and the ploughsbeam being less than ordinary, the force is exerted in a more direct line, and the mould-board kept always clean. The swell at the point o is sufficient to turn the earth properly.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The mould-board F, of shape described, and share'M, when combined as set forth.

2. The springs 7L and z'fwhen combined and operated as described.

3. The plough-foot D,`mouldboardF, share I\I, support G, standard E, and springs 7L and 1', when combined and'arranged substantially as described.

' FRANKLIN WATSON.
